Professional Applications & Engineering Value

This PVC plastic flat washer solves critical industrial challenges where metal washers fail. The gray PVC material provides inherent corrosion resistance, making it ideal for chemical processing, water treatment, and marine applications where rust compromises safety. With Durometer 65D hardness, it maintains compression integrity under sustained loads while the precise 0.531" ID ensures perfect alignment with 1/2" screws in electrical enclosures, plumbing systems, and food processing equipment. The 1" OD creates an optimal bearing surface that prevents surface damage to soft materials while the 140°F temperature rating supports use in heated industrial environments. These industrial plastic washers eliminate galvanic corrosion between dissimilar metals and provide reliable insulation in electrical assemblies.
